Differences in clinical characteristics between patients with diastolic heart failure and systolic heart failure / 天津医药

ABSTRACT

Objective To analyze the differences in clinical characteristics and risk factors in patients with diastolic heart failure and systolic heart failure. Methods A total of 2 088 patients with heart failure were divided into two groups, diastolic heart failure group (EF≥0.45,n=1 356) and systolic heart failure group (EF<0.45,n=732), according to ejection fraction (EF). The clinical features and related factors affecting the two types of heart failure were compared between two groups. Results There were higher age, higher proportion of women and higher proportion of hypertensive patients in dia?stolic heart failure group than those of systolic heart failure group, but lower rates of hypoalbuminemia, anemia, renal insuffi?ciency and hyperuricimia. There was higher incidence of functional class I and II in diastolic heart failure group. And com?pared with systolic heart failure group, there were higher levels of systolic blood pressure, albumin, prealbumin, cholesterol, sodium and serum chloride in diastolic heart failure group, but lower levels of heart rates, creatinine, blood uric acid, potassi?um and brain natriuretic peptide. Compared with systolic heart failure group, there were lower left ventricular end diastolic volume (LVEDV) and left ventricular end systolic volume (LVESV) in diastolic heart failure group. And there were lower RAS blocker andβ-blocker usage, higher statin usage in diastolic heart failure group. Logistic regression analysis showed that gender and hypertension were significantly correlated with diastolic heart failure, and hypoalbuminemia and hyper?uricimia were significantly correlated with systolic heart failure. Conclusion Our results show that there are differences in clinical features and risk factors in patients with diastolic heart failure and systolic heart failure. We should take the differ?ent treatment and prevention programs for the two kinds of heart failures.
